Abstract
The invention discloses high-performance composite conductive rubber, which comprises the following components in parts by weight: 40 to 60 parts of chloroprene rubber, 10 to 20 parts of ethylene propylene diene monomer, 5 to 8 parts of silane coupling agent, 6 to 10 parts of stearic acid, 2 to 5 parts of rhine powder 25, 15 to 20 parts of iron powder, 10 to 15 parts of number 46 machine oil, 2 to 5 parts of flame retardant and 10 to 20 parts of sulfur. The conductive rubber can be used for a liquid crystal display material, and can also be used for an electronic instrument robot, an explosion-proof switch, various voltage sensing elements and heating elements, and conductive performance and electrical performance stability/(Omega.cm) are less than or equal to 0.002.
Description
Technical field
The present invention relates to a kind of high-performance composite conducting rubber.
Background technology
Conductive rubber is that conductive particle is evenly distributed in silicon rubber by glass silvering, aluminium be silver-plated, silver-colored etc., by pressure, conductive particle is contacted, and reaches good conductivity.Military and commercially have an application.Its Main Function is sealing and electromagnetic shielding.Product can mold pressing or extrusion molding, has on chip or other die-cut shapes is available.Shielding properties is up to 120 dB (10 GHz).The conductive particle of filling in conductive rubber is when filling certain volume umber, be in contact with one another, form electronics continuous regime, when external electromagnetic field is outside to conductive rubber, strong hertzian wave is got on conductive particle unbound electron, unbound electron free movement, and unbound electron forms the electromagnetic field contrary with external electromagnetic field in moving process, interior external electromagnetic field is cancelled out each other, and reaches the effect that weakens electromagnetic interference wave; 2. another one principle is Conversion of energy, law of conservation of energy, and hertzian wave is got on unbound electron, in unbound electron moving process, because conductive particle is to have certain resistance, produce heat,---unbound electron motion energy---heat energy that is electromagnetic interference wave, to weaken electromagnetic interference wave.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of with low cost, high-performance composite conducting rubber that conductivity is high is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of high-performance composite conducting rubber, is grouped into by the one-tenth of following weight part:
Chloroprene rubber 40～60;
Terpolymer EP rubber 10～20;
Silane coupling agent 5～8;
Stearic acid 6～10;
Lay mattress loose 25 2～5;
Iron powder 15～20;
No. 46 machinery oil 10～15;
Fire retardant 2～5;
Sulphur 10～20.
The advantage of high-performance composite conducting rubber of the present invention is: conductive rubber provided by the invention, can be used for liquid crystal display material, and be also used as electronic instrument robot and explosion-proof switch, various sensing element and heating unit.Conductivity and electric performance stablity/(Ω cm)≤0.002.
